It can be refueled with the connector on the bottom, and reloaded too. This is a carrier/base fighter and needs a base to do those things. Ammo is stored in the cockpit and weapon inventories. Number 8 on the first hotbar is used for refueling, ammo is refilled in the inventory menu.

So how do you fuel this thing? Or give it ammo??

I'm glad you like it, after testing it online on unwilling targets I can confirm it will last.

Beautiful! Hope to build them soon. I love the addition of the cockpit behind a layer of glass placed into the front of the ship. Very neat and what Ive been looking for. Thanks!
